-iMjPRovEMEur In HEATING STOVES;

"1119 Schedule referi'ed these Letters Patent and making part of thelenme. A

Be it known' that I, NA'rHAnPnRmsmof Kalamazoo, county of Kalamazoo and State of'Michigan, have invented certain new and useful'-Improvements in Stoves and Furnaces," of which the following is a full, clear, and exactfdescriptiom reference being had to the accompanying drawings, making part 'of this specification, in which-- Figure 1 is a perspective view of a stove embodywhich carry the. hot" air and smoke down around the baseof the stovc,*thereby increasing largely the heatrng-surt'ace, there occurs 'a; great waste of heat, as a verylar'ge proportionof it. escapes into the chimney,

-W1th a view'to save and utilize this heretofore wasted heat, I have iuventedthe'following improvements; which'consist in-'- First, -the combinatiouof an auxiliary heating-cylmderror' chamber, with a top or face-plateprovided with boiler-holes adapted to'be used for cooking-utensils, and a series of hot -andcold-air; fines, in' such manner-that the; heatinaybcused 'for warming the room, or for cooking, or both, at will;'

Second, in such an arrangement of smoke-fines and top-plate as will permit the useofthe centralportio'n of the stove 'for cooking purposes and Third, in a novel combination of parts, by which certain advantages in controlling the heated currents are obtained, as willrbe hereinafter explained.

' In the drawings Arepresents the" base of the stove, which may be made in any well-known or desired form, and should be provided with a damper, for controlling the amount of airtto headmitted to the fire;

-B is an outer shell or'cylinderfmadc preferably of sheet-iron, as is customary in the ordinary heatingstoves, and provided with a door, 13. v l

The fire-box employed in this stove is furnished :ivizlaifla grate and lining, and need not be described in door B or 'through a chute,-o r a"series of chutes or pockets,'B, arranged in convenient positions around the outside of shell B, in which latter case pockets;

This chamber.

' "G is an auxiliary heating-chamber, of less diameter than cylinder B, and placed concentrically within saidfiilinder; I

Chamber 0 'I make preferably of cast-iron, and form it with a-hahge around its upper or open end, so as to fit closely the upper endof shell B, as do the cast-iron tops in the present'construetion of stoves. I

The. lower'endbf this chamber is closed, and made slightl y conicalin form.

ID is a c'old air fiue-extending'through the annular space between thecylindcr and chamber,'for the pur' pose of admitting air into chamber (l. t

d is a damper in flue-D. There is one of these flues upon each side of the stove.

E E are hot-air fines, conneotingwith the interior of chamberO.

cc are dampers in flues E.

F is a drum, into which the smoke and hot air are conducted from the stove, through pipes orv fines f, one of which is located at each end of this'drum. is 'a flue leading from drum F tothe chimney.

H is :a plate provided with boiler or griddle-holes,

and is made preferably separate from a the flange cast or formed upon chamber 0. When made in two pieces, the-parts should fit quite accurately, in order thatthe air may be confined until a suihcient degree ofheat shall lie-obtained.

In using my'improvedstove'for heating purposes only, the upperpart of the chamber may be left en'- tirely o'pen,.hy the removal of plate H, except in case it-is desired to heat'an upper room or rooms, by

conveying the heat thence, by means of pipes connecting with: flues E E, in which case the plate means of damper. c c, and the griddles used for cover ingthe boiler-holes. I

Under ordinary circumstances it will he found ad visable to keep dampers (1 wide open, as'they will admit a current of cold air into the interior of chamber 0, where it will become-heated and escape from the top of the chamber, thus keeping up a free circulation of air .jin the room, and preserving .it much purer.

When using the stove for cooking purposes, it will sometimes be found necessary to close dampers e e entirely,iu order to bring the temperature-within chamber'Q up to the required point, and it maybe advisable to close dampers (Z for the samereason.

For baking,'I-remove plate H and set an oven in itsplac'. This oven may project down into the chamber if thought best. t r l The sainepprinciples may he introduced into any B, can be made to take the place of the magazines such hro'difications indetails as shall be required.

They can also be applicd to'rnany kinds of. furnaces,

used in many of the better class'of stories;

by which modifications a portion of the heat may be 2; The removable plate H, provided 'with boiler-v diverted for cooking, andthe trouble of an extra firev holes, in combination with chamber 0 and shell or avoided. casing B, substantially as set forth.

What I claim as new, and desire to secure by Let- NATHAN PARRISH. ters Patent, is-

l. The combination of the outer shell or casing 13, the inner chamber or cylinder 0, top-plate H, proridedwith boiler-holes, flues E E, and flues D, substantially as and for thepurpose set forth.
